ACH Correction Codes
Payment funded, but account info needs updating for future transactions. Status shows CORRECTION instead of FUNDED.
Why C-Codes Happen
Usually occurs when banks merge—old routing/account numbers get updated.
C-Code Lookup
| Code | Problem | Fix |
|---|---|---|
| C01 | Wrong Account Number | Use corrected account # from details |
| C02 | Wrong Routing Number | Use corrected routing # |
| C03 | Wrong Account + Routing | Use both corrected numbers |
| C04 | Wrong Account Name | Update name |
| C05 | Wrong Transaction Code | Fix trans code |
Example:
C01 123456789 = Use 123456789 as new account # next time.Where: Transaction details → Status Description shows corrected info.
Warning: Use corrected info or next payment returns as X-code (blocked).
